Yes, now that you read it back to me slowly it makes some sense.  And that
order is also why we cannot, say, get rid of `-g` in there.

Yep.  My time-tested local rev.dep system does the same, I just lulled myself
into believing there was another way. But that was a mirage.

So thanks for pointing that out, freeing me to worry about other non-issues. ;-)

Having a bit of a puzzle with a package at work (which I can't share).

In src/Makevars I override CC, CXX, CXX11, CXX14 to point to a specific
(version) of g++ on my system, say g++-x.y.  I also set CXX_STD=CXX14

Only it doesn't work. I need an extra dot.RMakevars and an invocation via

   R_MAKEVARS_USER=~/git/thatpackage/dot.RMakevars R CMD INSTALL .

or else the values from R's default Makeconf come through.

How could that be?  I have invoked R CMD INSTALL probably thousands of times,
and most got it to what I wanted but setting values in it.  What could be
wrong here?

R 3.4.2; Ubuntu 17.04.

Puzzled,  Dirk




According to section 1.2.1 "Using Makevars" in Writing R Extensions, 
R_HOME/etcR_ARCH/Makeconf is included after Makevars, so what you're
